my diagnosis

There is only one state-admittedly an unusual state, but not one that can be stigmatized as pathological-in wich it does not do this (ego maintains clear and sharp lines of demarcation). At the height of being in love the boundary between ego and object thretens to melt away. Against all the evidence of his senses, a man who is in love declares that 'I' and 'You' are one, and is prepared to behave as if it were a fact.
